UNiTEl) @EATES PATENT ALPHONSE BEBNARD-SGHMOLLE, OF LONDON, ENGLAND.

SIPHGN.

To (ZZZ whom it may concern:

Be it known that I, Anrriorzsn BERNARD- Scrnzonnr, a citizen of the United States, resioing at London, England, have invented certain new and useful Improvements in Siphons, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in siphons and particularly to improvements in siphons adapted for use w'th bottles,flasks and like containers or receptacles and to fit in the neck thereof; and an object of this invention is to provide a siphon of the type just mentioned which will prove simple in construction, relatively cheap in manufacture and highly eflicient in use.

Another object of this invention is to provide a siphon of the character described with means for charging the bottle with an expandible fluid, such as a suitable gas.

A third object of this invention is to provide a siphon of the class referred to with a blow-0E device which will prevent the bottle from becoming overcharged with the gas.

A further object of this invention is to provide a siphon with an efficient gas-check or fermeturefor sealing the mouth of the receptacle.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure l is an elevation, partly in section, of a bottle provided with my new siphon; Fig. 2 is a vertical central section through the gas reservoir and the means controlling the outlet thereof; and Fig. 3 is a detail in section showing the connection between the gas-reservoir and the interior of the bottle which contains the liquid to be dispensed.

The interior wall of the neck or mouth of the bottle Z) is formed with a circular groove 0 in which is fitted a rubber gasketring (Z which is carried by the siphon-pipe e and which rests upon the washer-nut f formed thereon. The lock-nut f serves to hold the latter in its adjusted position. The siphonpipe 6 passes through the bore of a tubular stopper 9 the inner end of which rests upon the top of the gasket-ring (Z and the outer end of which is formed with a flanged head g which is adapted to rest on the top of the bottle Z) and to cover the mouth (6 thereof. The part c of the siphon-pipe e which projects just above the head 9 of the stopper 9 is screw-threaded and on it is Specification of Letters Patent.

mounted a wing-nut it by turning which in the proper direction pressure may be brought to bear upon the stopper 9 and by the latter transmitted to the rubber gasket-ring (Z.

whereby the latter is compressed between the inner end of the stopper and the washernut f and is forced tightly into and against the wall of the circular groove 0 to form a gas-tight joint at this point. Hence, the gasket-ring (Z serves as a gas-check or fermeture to prevent the escape of gas from the bottle by way of the mouth thereof.

The upper end of the glass siphon-tube 2' is provided with a metal sleeve or collar j the top of which is cupped and interiorly-threaded and is thereby adapted to be screwed upon the threaded portion a" of the metal siphon-pipe e which lies just below the washer-nut f. The lower end of the glass siphon-tube 7; extends, as usual, almost to the bottom of the bottle Z).

Above the threaded portion 6 the metal siphon-pipe e is formed with a nozzle or spout 7s and is provided wit-h a Valve or tap m which may, of course, be of any suitable type and which forms in itself no part of this invention. On the valve-casing m of the valve m and integral therewith is formed a hollow support or post a having a nipple 0 into which is screwed the threaded end of the outlet-pipe p which leads from the bulbshapecl gas-reservoir g. The latter is adapted and designed to hold compressed carbonic acid gas or other suitable expandible fluid. On its side opposite from the nipple 0 the hollow post 'It carries a cup 1" in which is mounted a diaphragm s which is adapted to bear against the projecting end of a valve I? mounted in the outlet pipe or passage 9. Into the cup 7* is screwed a perforated screwcap a through which extends a plunger 11 the inner end 01 of which is adapted to press against the diaphragm s for the purpose of opening the valve t. The chamber a in the hollow post "It is connected by a nipple n and a piece of rubber tubing to with a nipple 50 which communicates with the upper end of the passage 6* formed in the siphonpipe c (Fig. 3) that is, the connection between the nipples n, a lies outside the valve-casing m and consists of a bit of rubber tubing iii. In case too much gas is inadvertently allowed to flow from the gas-reservoir Q or in case the valve t should leak, excessive gas pressure thus produced will be relieved by the gas leaking past the ends of the rubber tubing 20, or by its blowing the latter ed the nipples. EiltlllCQ; the rubber tubing serves as a sort of safety valve or blow-off device in case the pressure of the gas in the flask Z) rises too high. The outlet for the gas fiow ing from the gasreservoir Q into the flash I) through the siphon-pipe is the hole 3 which is in the threaded part c of the latter and which forms the inner or lower end of the passage 6* (Fig. 3).

It will be observed that the structure hereinbefore described is very compact and S'l11lple in its construction. Since the passage 0* for the gas lies within the wall of the siphon-pipe or siphon-tube e, the exterior of the wall may be threaded and the bottle sealing devices (Z, g, it may be mounted directly on the wall. By the provision of the passage 97/, to, :0 the gas-reservoir outlet at Z3) is connected with the inlet end of this passage 0; and since this passage lies outside of the siphon-tube and leads the gas thereby around the outlet Z: for the discharge of the beverage, it is practicable to malte this conduit include a blow-off safety device, such as the readily detachable rul A ber tubing to.

I claim:

1. In an apparatus of the character de* scribed the combination of a valve-coir trolled gas-reservoir; a siphon-tube which carries said gas-reservoir and which is provided with a valve-controlled outlet for the beverage, the bore of said tube being arranged to communicate with said outlet and the wall of said bore being provided below said outlet with a passage for the gas; and a conduit which leads the around said outlet and connects the outlet from said gasreservoir with said passage and which includes a safety blow-oil member.

2. In an apparatus of the character described the combination of a valve-eontrolled gas-reservoir; a siphon-tube which carries said gas-reservoir and which is provided with a valve-controlled outlet for the beverage, the bore of said tube being arranged to communicate with said outlet and the wall of said bore being provided below said outlet with a passage for the gas; a conduit which leads the gas around said outlet and connects the outlet from said gas reservoir with said passage and which includes a safety blow-off member; and boteaasea tle-sealing means mounted on said wall above the outlet end of said passage.

In an apparatus of the character describeth the combination of a siphon-tube having a valve-controlled outlet with which the bore of said tube is arranged to communicate for the discharge of the beverage, the wall of "aid here being provided with a passage for gas; a valve-controlled gasreservoir; a conduit which connects the out let of the latter with the inlet of said passage and which is provided with a safety device for preventing too high back pressure of the gas; and bottle-sealing means mounted on said wall above the outlet of said passage.

l. in an apparatus of the character dcscribed, the combination of a SlPllOll-tlllJt aving a valve-controlled outlet with which the bore of said tube is arranged to communicate for the discharge of the beverage the wall of said bore being provided with a passage for gas; a valve-controlled gas-reservoir, a safety blow-off device which connects the latter with the inlet end of said passage; and bottle-sealing means mounted on said wall above the outlet of sale passage.

5. A siphon l'iaving a siphon-tube which is provided with a valve-controlled outlet for the beverage, said. tube being formed above said outlet with a passage for gas and the bore of said tube. below said outlet being arranged to communicate with said outlet; the wall of said bore being provided below said outlet with a passage for gas; a blowolf safety-device which lies outside of said tube and which connects said passages for gas; means for forcing through said passages and device; the latter conducting the gas from said means around said outlet into the passage formed in the wall of the bore of said tribe below said outlet and said wall being exteriorly threaded; and bottle-sealing means mounted on said exteriorlg,-threaded wall.
